What Factors Affect Belt Filter Press Price and How to Choose the Right Model?
Jul 18, 2025
The belt filter press is a dewatering machine that is mainly used in the contexts of sludge treatment, wastewater recovery, and solid-liquid separation, and is still one of the most widely used and cost-effective dewatering machines. But still, many buyers are stuck at the same question: What are the criteria for filter press pricing, and how to select from the various models available the most appropriate one for my application?
As the article shows, the search for the best and cost-saving purchase is also possible by exploring the key pricing factors in this field and at the same time comparing some other options, such as the Membrane Filter Press and the Vacuum filter press, to know which one to buy wisely.
What Is a Belt Filter Press?
A belt filter press is a continuous-operation dewatering system that uses two moving filter belts to squeeze water out of sludge. It’s often used in municipal wastewater plants, mining operations, food processing, and chemical industries. Compared to batch systems, it offers high throughput and energy-efficient performance with moderate investment costs.
What Influences Belt Filter Press Price?
The belt filter press price varies depending on several technical and operational factors:
- Machine Size and Capacity
Larger models with higher daily throughput (e.g., 10–30 m³/h) are naturally more expensive due to bigger belts, frames, and drive systems. - Material of Construction
Frames and rollers made from stainless steel or corrosion-resistant alloys increase durability but also raise the price. - Automation Level
Models with automatic belt alignment, tensioning, washing, and PLC control systems typically come at a premium, but reduce labor costs long-term. - Filtration Performance Requirements
If your sludge has low solids content or requires high dryness levels, specialized belt configurations or pre-dewatering systems will affect total cost. - Brand and After-Sales Service
Well-known manufacturers like JingJin Filter offer proven performance, quality parts, and technical support—factors worth the investment.
Belt Filter Press vs. Membrane Filter Press
If you’re seeking higher dryness or filtering efficiency, you may be considering a Membrane Filter Press as an alternative. This system applies high-pressure air or water to membrane plates after initial filtration, squeezing the cake further and reducing final moisture content to as low as 30%.
Pros of Membrane Filter Press:
- Achieves higher cake dryness
- Suitable for difficult-to-dewater sludges
- Better for small batch or high-value material separation
However, the upfront cost is significantly higher than a belt press. Also, it operates in batch mode and has longer cycle times, making it less ideal for continuous-flow applications.
When to Consider a Vacuum Filter Press
For operations involving fine particles, temperature-sensitive materials, or filtrate recovery (e.g., in mining or pharmaceuticals), a Vacuum filter press may be the best fit. This system uses vacuum suction to pull liquid through a filter medium, offering gentle yet efficient separation.
Compared to both belt and membrane presses, vacuum systems:
- Are ideal for lightweight or highly filtered slurries
- Often require higher investment and maintenance
- Offer superior filtrate clarity in specialized industries
